tutes the forward scraper blade 22. EX 49 which has its lower edirc constituting;` :in

tending across the rear portion of the frame an oppositeli7 inclined mold board 23 har ing its ends provided with ball members 24 engaged within soclcts 25 on 'the confrontine` faces ot the side bars. The rearmost end ot this mold board is loca-ted adjacent the arch 12%, The lower edge of this mold board constitutes the rear cutting' blade 26. The numeral 27 designates brace rods which are connected with the bar 16 and with the mold board 19. and the numeral 28 designates similar brace bars connected with the bar 16 and the rear mold board should be stated that the numeral 29 designates inclined brace bars which are connected with the bar 1G and with the side bar l0 whereby to reinforce thev structure.

Located at the rear portion ot the frame is a movable trame 80 termed of a truss rod structure oi archlike formation and within which. are journaled ground engaging wheels The extremities of the frame 30 are provided with lateral extensions 32 constituting trunnions which are rotatable within bearinns secured to the bar l0. Secured. to the uppermost member ot the frame 30 are forwardlv converging rods 34 which are connected with link 35 which is pivotallv eon- `nec'ted with a control. lever 3G pivoted upon the plattorm A1..7 and provided with a strip release latch 3'? cooperatineF with a notched segment 38 wherebv to hold the lever 36 in adjusted position. By adjustingr lthe lever 36 backward or forward it will be apparent that the tra-me 30 may be swungr upon its trunnions 32 and this will result in raising or lowering they rear end of the main frame for varying: the depth of penetration of the rear blade 26.

llitending;y diagonally at the forward corners oi the main frame are bars 39 upon which are pivotallj.7 mounted the depending7 arms 40 of a .trame which includes a horizontal bar 4l and swivell'v mounted upon the lower ends ot these arms 40 are voices l2 within which are journaled wheels 43. Bv this construction it will be seen t-hat the wheels 43 are free to turn in anv direction in the same manner as a caster. Connected with therod 4l. isa rearwardly extending' reach rod 4.4- which is pivotallv connected with a lever 45 pivoted upon the platform i7 and having' a grip released latch 46 cooperating with a notched segment 47. Bv this construction it will be seen that by movine the lever 45 the trainer including the arms 4th mav be rocked upon the pivots 40 .and in this wav the forward end ot the main trameinav be moved un or down with respect to the .O'round so as to varv the depth ot `penetrate'on oi the forward cutting blade22,

Hin-ged upon one side bar l() adjacent the arch 14, as shown at 48, is a mold board auxiliaryv scraper blade fill. lonncctcd with the Ltree end oil' this mold board IIS) is :i chain or other iiexihle. uicinbcr 1' l. which is connect ed with thc lonfrue 52 or other dralt device, which secured centrallyY to the 'front har ll. Also connected with the rec end of this mold board 49 is a rod which has its rcar end pivotallv connected with a lever 5i, ha va `grip released latch 5l cooperating with a notched segment ln the operation oi the device it will he seen that when it is dru wn along); the ground bv animals or a tractor. the blades 22 and 2G will scrape the `ground to a `greater or less depth. dependinn` upon the adjustment of the rear 'frame 30 and the forward frame ll` as will be readily apparent, the high spots 4being ol curse out down and the diri rcmoved theretrom being scraped into the low spots so that a level surface will be left after the device has passed over. Tlv adjustiiuf the lever so as to press and hold the mold board 49 and blade 50 in a downwardlyY iuclined position, it will be ainiarent that a ditch alongside, the road may he scraped, the dirt drag ed loose bv the blade 50 passing through the' arch 14 in the path of travel ot the blade 22 and this additional dirt will of course be distributed alone; the roadway',

From the Vloresfoing' description and a studv oli the drawings it will be apparent that l have thus provided a simply constructed and consequently inexpensive road scraping` and leveling device which will be unusuallv eliicient in operation and which will not only,7 operate to level :i road but which will also scrape or clear a ditch at the same time. Owin'c` to the considerable length of the device it is apparent that irregularities in the road will be eliminated as the device will veryv etiiciently cut down the high spots and scrape this surplus dirt into the hollows. lt will be observed that the control nieclun nism is ver)Y simple and involves the adji'istnient of thc l'ran'ie with respect lo the ground. the main blades being: enlirclv sla-- tionarv with respect to thc. frame I lVhile l ha vc shown und lcscrilud the pre Vterred einl'iodiuicnt o'f nrv invention. it is of course to be luulcrstowl that l reserve the rig-rbtto multe such chances in the forni. construction and arraiufement ol parts :is will not depart l'rom the spiril` oll thc invention or the scope o the snbjoincd claims.

vl-laviugr` thus described in v invention l claim l, A device oli the character described comprising; an elongated rectangular frame. a draft tonjnie connected therewith. trans-- verse scraper blades mounted thereinn an auxiliary mold board and blade pivotally mounted at one side of the main `frame and evtendingr laterallyy therefrom. a flexible member connected with the free end of scraper mechanism including a mold board pivoted at one side of seid frame, e flexible member connected with seid mold board for M limiting outward swinging movement thereof, a, notched segment stationarily mounted upon the frame, a lever having e grip released locking pand (zo-operating with said segment `and e link connected With said lever 20 and with said mold board. i ln testimony whereof l eix my signature.
